Question

If the lateral surface area of a cube is 784 cm2
and
surface area of cube is equal to surface area of cuboid,
then find the surface area of cuboid

Answer 1

Answer:

We know that the, Lateral Surface area of Cube is= 4a^2

Then,

The value of the cube side is -

4a^2=784

or, a^2= 784/4

or, a^2= 196

or, a=√196

or, a= 14cm.

Then,

Surface area of Cube is- 6a^2

6a^2

=6×(14) ^2

=6×196 cm^2

= 1176 cm^2

Hence,

According to the question-

Surface area of cube= Surface area of Cuboid.

Then,

The surface area of cuboid is - 1176 cm^2
